Due to large variations in the quality of reporting, Airwars provisionally grades allegations of civilian harm using a standardised methodology across all belligerents and conflicts. The five categories are explained in full on our Methodology page. Individual events are recorded in the Civilian Casualties pages.
Airwars has tracked thousands of reported events in which Russian strikes in Syria or Coalition military actions in Iraq and Syria have allegedly killed civilians. While these raw claims should be treated with caution, they can nevertheless help us to understand trends over time. In March to May 2016 for example, alleged Russian incidents fell by 75% – most likely as a result of a regional ceasefire then in place.
